Beyond the Standard Model for Hillwalkers
, 1998 In the first lecture, the Standard Model is reviewed, with the aim of seeing how its successes constrain possible extensions, the significance of the apparently low Higgs mass indicated by precision electroweak experiments is discussed, and defects of ...

Road map through the desert: unification with vector-like fermions
Journal of High Energy Physics, 2019 In light of null results from New Physics searches at the LHC, we look at unification of the gauge couplings as a model-building principle. As a first step, we consider extensions of the Standard Model with vector-like fermions.

In search of a UV completion of the standard model — 378,000 models that don’t work
Journal of High Energy Physics, 2018 Asymptotically safe extensions of the Standard Model have been searched for by adding vector-like fermions charged under the Standard Model gauge group and having Yukawa-like interactions with new scalar fields.

Unification with vector-like fermions and signals at LHC
Journal of High Energy Physics, 2018 We look for minimal extensions of Standard Model with vector like fermions leading to precision unification of gauge couplings. Constraints from proton decay, Higgs stability and perturbativity are considered.

Beyond the Standard models of particle physics and cosmology [PDF]
Bled Workshops in Physics, V. 19. PP.314-326, 2018, 2018 The modern Standard cosmological model of inflationary Unvierse and baryosynthesis deeply involves particle theory beyond the Standard model (BSM). Inevitably, models of BSM physics lead to cosmological scenarios beyond the Standard cosmological paradigm.

Neutrinos from the Early Universe and Physics Beyond Standard Models [PDF]
arXiv, 2014 Neutrino oscillations present the only robust example of experimentally detected physics beyond the standard model. This review discusses the established and several hypothetical beyond standard models neutrino characteristics and their cosmological effects and constraints.

Detecting dark matter with Aharonov-Bohm
Journal of High Energy Physics, 2019 While the evidence for dark matter continues to grow, the nature of dark matter remains a mystery. A dark U(1) D gauge theory can have a small kinetic mixing with the visible photon which provides a portal to the dark sector.

Saxion cosmology for thermalized gravitino dark matter
Journal of High Energy Physics, 2017 In all supersymmetric theories, gravitinos, with mass suppressed by the Planck scale, are an obvious candidate for dark matter; but if gravitinos ever reached thermal equilibrium, such dark matter is apparently either too abundant or too hot, and is ...

Nonstandard cosmologies from physics beyond the Standard model [PDF]
arXiv, 2016 The modern cosmology is based on inflationary models with baryosynthesis and dark matter/energy.It implies extension of particle symmetry beyond the Standard model. Studies of physical basis of the modern cosmology combine direct searches for new physics at accelerators with its indirect non-accelerator probes, in which cosmological consequences of ...
